The quad-data-rate (QDR) and double-data-rate II (DDR-II) specifications will be used to design new high-speed SRAMs, commonly found in networking products. The QDR spec, which takes clock speeds up to 333-MHz, has been submitted to the JEDEC industry council for evaluation.

Initial silicon for an 18-Mbit device is under evaluation, the three companies said, using a 13-mm x 15-mm FBGA package optimized to carry the designs through future 18-, 36-, and 72-Mbit extensions.
